When you're an individual dev, if you think ads are bullshit, tracking is bullshit, /r/all is bullshit, non-chronological feeds are bullshit, infinite scroll is bullshit, promoting ragebait/clickbait to boost engagement is bullshit, gold/coins/stickers/premium is bullshit, inline images are bullshit, and anything that negatively impacts responsiveness/performance/stability is bullshit - it's within your power to improve the product - often by simply not implementing them.

When you're a dev for a big corporation like reddit, though, if your boss wants some bullshit that makes the product worse but more profitable, it's your job to make the product worse but more profitable.
